Which is the next logical step in balancing the given equation? 3CO(g) + Fe2O3(s) Fe(s) + 3CO2(g)
2 answers:
Answer : The correct option is, (C) Place the coefficient 2 in front of elemental iron.
Explanation :
Balanced chemical reaction : It is defined as the number of atoms of individual elements present on reactant side must be equal to the product side.
The given unbalanced chemical reaction is,
This chemical reaction is an unbalanced reaction because in this reaction, the number of atoms of iron are not balanced while all the atoms are balanced.
In order to balanced the chemical reaction, the coefficient 2 is put before the 'Fe'.
Thus, the balanced chemical reaction will be,

<u>We want the molar mass (gfm) of Fe and FeS.</u>
Fe = 55.8 g/mol and FeS = 87.8 g/mol (55.8 +32.0).
<u>Explanation:</u>
We want ratio between Fe:FeS 8:8. This comes from the coefficients of the equal chemical equation.
Now we set up conversion factors following the roadmap from above.
Unit we want in the numerator, unit to cancel in the denominator.
Multiply the numerators, and divide the denominators.
The outcome is 243.82 g of ferrous sulphite
By the above given formula we can find any amount of Fes produced by any amount of ferrous react with sulphite.
